چکیده | ||
هدف این پژوهش تولید ماست فراسودمند با استفاده از ایزوله پروتئین سویا بود. از سطوح 5/0، 0/1 و 5/1 درصد (حجمی/وزنی) ایزوله پروتئین سویا در ماست کمچرب استفاده شد و ویژگیهای فیزیکی شیمیایی (pH، اسیدیته، ماده خشک بدون چربی، آباندازی، ویسکوزیته)، میکروبی (کپک و مخمر) و حسی (رنگ، سفتی، طعم، ترشی، تندی، کهنگی و کپکی و پذیرشکلی) در روزهای اول، هفتم، چهاردهم و بیست و یکم بررسی شد. نتایج نشان داد که افزایش غلظت ایزوله پروتئین سویا موجب افزایش معنیدار اسیدیته، ماده خشک بدون چربی و ویسکوزیته و کاهش معنیدار در آباندازی ماست شد، اما بر pH تاثیر معنیدار نداشت (05/0 > p). مطلوبترین ویژگیهای حسی در روزهای اول آزمون و در نمونههای ماست کنترل و نمونههای حاوی 5/0 و 0/1 درصد ایزوله پروتئین سویا مشاهده شد (05/0 < p). نتایج نشان داد که استفاده از ایزوله پروتئین سویا میتواند به دلیل وجود ترکیبات تغذیهای مناسب به عنوان یک پیشنهاد در تولید صنعتی ماست کم چرب فراسودمند در نظر گرفته شود. | ||

چکیده [English] | ||
The purpose of this study was to produce the low fat yogurt using soy protein isolate. The soy protein isolate in concentrations of 0.5, 1.0 and 1.5 was used in low-fat yogurt formulation and the physicochemical properties (pH, acidity, non fat dry matter, syneresis, viscosity) and microbial (growth of mold and yeast) and sensory properties (color, firmness, taste, sourness, spiciness, oldness and moldy and overall appearance) were evaluated on 1, 7, 14 and 21 days of storage. The results showed that with increase in soy protein isolate concentration, acidity, non fat dry matter and viscosity were significantly increased and the yogurt syneresis was significantly decreased, while it had no significant effect on pH (p > 0.05). The most desirable sensory properties were observed in the first days in the control and samples containing 0.5 and 1.0% soy protein isolate (p < 0.05). The results showed that the use of soy protein isolate due to its nutritious compounds can be considered as an offer in the industrial production of functional low fat yogurt. | ||
